I believe the original theatrical versions are dead in the water. A petition such as this one is about the only thing that will resurrect them. 21,672(and still counting) confirmed signatures may not be as much as 30,000, but it's still a lot. Even if he doesn't release the original versions come 2005, there's still a chance he'll do it for the 30th anniversary of Star Wars in May of 2007. There's even a really slim chance that he might change his mind about it for no apparent reason.
